Common and vulgar people ascribe all ills that they feel to others; people of little wisdom ascribe to themselves; people of much wisdom, to no one.

Don't just say you have read books. Show that through them you have learned to think better, to be a more discriminating and reflective person. Books are the training weights of the mind. They are very helpful, but it would be a bad mistake to suppose that one has made progress simply by having internalized their contents." Translation by Sharon Lebell

Know you not that a good man does nothing for appearance sake, but for the sake of having done right?

What concerns me is not the way things are, but rather the way people think things are

We must not believe the many, who say that only free people ought to be educated, but we should rather believe the philosophers who say that only the educated are free

People are not disturbed by things, but by the view they take of them.
